Depending on your usage and environment, it’s recommended to replace the filter every 3–6 months — replacements are available on Amazon.
Here’s what BuzzFeed writer Jenae Sitzes has to say about the it:
“I picked this air purifier up a while back to help manage the ~smell~ that sometimes wafts from my cats’ litter box when it starts to get full, and to help keep my NYC apartment air cleaner in general. I’m also (lol) extremely allergic to cats, and though I get allergy shots for this, it’s also nice to help cut down on the pet dander for myself and any visitors with allergies. This thing makes a DIFFERENCE. It cuts down on any noticeable smell from the cats, my air feels cleaner, and my allergies are usually non-existent in the apartment.
I was *especially* grateful to have this recently when Canadian wildfires brought smoke all the way down to NYC, where the AQI (air quality index) was over 400 at some points (for those who don’t know, that’s BAD). It helped keep the air inside my apartment as clean as possible, which made me feel better for myself and my kitties. Since I have a one-bedroom, I’ll likely pick up a second one just so I don’t have to move it back and forth at night. Oh, and it’s fairly quiet — it basically functions as white noise, which can be handy if you run this at night in the bedroom too.”
